Some glyphs [fi and fl, particularly] should not be ligated in a fixed-width font; they don't offer any readability enhancements and, in fact, hinder usage by the visually impaired.
What version are you using? We removed the ligature rules a long time ago, now they're only discretionary.
Ubutu Gutsy has 2.19 and not any later versions.
I've just checked our 2.19 version, there is no "liga" (ligature) rule defined for the "fi" and "fl" ligatures, only "dlig" (discretionary ligature). Only liga is applied by default, not dlig (except when you managed to patch Qt or Pango in such a way that it does, of course). Can you post a screenshot?
Really, I have no idea how you get that ligature. Is that a normal Gnome application (I don't recognize it). Do you get the ligatures as well in Gedit? In FireFox? Could you manually install the latest DejaVu Mono (don't install Sans from 2.22, it's buggy) and check if you still get ligatures?
Yes, I get the ligatures in Gedit and Firefox. I'll install the latest DVSM and see if that helps any, yes.
It seems to be working fine if I manually install DVSM into my ~/.fonts, even though the system-installed version that ships with Hardy [updated to Hardy last night] exhibits the issue I was reporting.
I'm thinking I should take this up with Ubuntu now; do you agree?

I'm using an up to date Ubuntu Hardy but I cannot reproduced the bug. ttf-dejavu 2.22 is currently on Hardy.
What do you get with the following command?
fc-list "DejaVu Sans Mono:style=Book" file
I get the following:
aphrael@kitsune:~$ fc-list "DejaVu Sans Mono:style=Book" file

Where does /home/aphrael/.fonts/DejaVuSansMono.ttf come from?
/home/aphrael/.fonts/DejaVuSansMono.ttf is from your (DejaVu's) packaging of 2.22.
